About

I’m a Senior Android Engineer with 8+ years of experience building, scaling, and optimizing Android applications for millions of users. I specialize in modern architecture (MVVM, Clean Architecture), Jetpack Compose, and performance engineering — with a focus on reducing crash rates (ANRs, OOMs), cold start times, and UI lag. At Tinder, I’ve led the development of major features like Explore Compose, and drove performance initiatives as a leader in the Performance Working Group, where I used AI tooling (Codex, Firebender) to assist in diagnosing system bottlenecks. I’m passionate about crafting scalable, maintainable code and empowering teams to deliver top-tier user experiences. 🏆 Tinder All-Stars (2021) 🏆 3× Hackathon Champion (2020–2022)
